Top Tech Startups in Austin, TX in 2026

Behind every opportunity is someone who introduced you. The investor who funded your company. The customer who changed its trajectory. The person who introduced you to your co-founder, next hire, mentor, or partner. Yet our professional networks have never been larger, and we still struggle to answer a simple question: Who should I know? Introd helps you discover the people you should know, understand how you're connected, and find the right path to an introduction. We’re building the relationship layer for opportunity: intelligence that turns fragmented professional networks into an understanding of who knows whom, which relationships actually matter, and where the strongest opportunities exist. Underneath Introd is a relationship graph that brings together signals across the places professional relationships already live. AI and graph intelligence help identify relevant people, understand relationship strength, rank connection paths, and surface opportunities that would otherwise remain hidden. For a founder, that might mean discovering the right investor or customer. For an investor, the right founder. For an executive, a strategic partner or key hire. For a community, it means turning hundreds or thousands of members into relationships that actually create value. We don't believe the future of professional networking is another feed, another directory, or collecting more connections. It's knowing the right people at the right moment. That’s what we’re building. The right people. Stronger relationships. Real opportunities. You’re one introduction away.

When an operator stops at a Mudflap network truck/fuel stop, when there they open the Mudflap app and select the fuel stop where they want to fuel. One tap of a button will then ''generate a fuel code -- it's a numeric code unique to you and that particular truck stop,'' Desai said. That code is then what you show to the fuel desk clerk, and how they ID you as a Mudflap customer, turning on the pump for you. Then, essentially, you're done. Mudflap was established in 2016 by Sanjay Desai in Palo Alto, California.
